Before you believe a bad review about us

We would like to respond openly to every negative review about us. Many are posted anonymously, so we cannot reach those customers directly. This open letter is our reply, and we would be grateful if you took a moment to read it.

But here is what a one-star review will never tell you:

  • We import from 70+ official distributors. That is why you pay far less than local retail — and why delivery takes longer. We publish the date before you pay, never after.
  • You can pay only when your goods land in Johannesburg. Pay on Arrival, no full payment up front. Ask yourself what scammer offers that.
  • Nobody has ever lost money with us. You get the product, or you get a refund. There is no third option, and there never has been.
  • We are part of the ITwork group — ten years trading in Europe, nine stores, thousands of positive reviews.
  • Johannesburg and Cape Town stores open this year — real shelves, real stock, walk in and buy the same day.

We are not satisfied with our review scores, and we are not going to fix them by hiding anything. We are fixing them by being faster, clearer and easier to reach than any reason to complain.

Read the full letter — photos and video of real shipments, and a straight answer to every accusation.

Problem with an order right now? Write to [email protected], [email protected] or [email protected] — answered the same business day. The letter also lists our group and store owners' contacts.

Designed for professionals who need more screen space, the ProLite X4373UHSU offers a seamless solution for multitasking and multi-device workflows. The 43'' panel delivers rich colours, sharp 3840x2160 resolution and wide 178° viewing angles, with 450cd/m² brightness ensuring excellent visibility in any lighting. For added flexibility, the monitor supports dual mode, allowing you to work in 3840×2160 for detailed content creation and data-heavy applications, or switch to 1920×1080 at 120Hz for smoother motion when displaying dynamic content or live feeds. The USB-C input with 95W Power Delivery, integrated KVM switch and four-port USB hub make it easy to connect, control and charge multiple devices through a single setup. Flicker-free technology and a blue light reducer help minimise eye strain during long sessions, while the included remote control offers instant access to key settings. Ideal for content creation, financial dashboards or control environments, this all-in-one monitor maximises clarity, comfort and productivity.

Adapt your display to match your pace

Switch seamlessly between two optimised modes to suit the task at hand. Dual Mode empowers your workflow by offering crystal-clear 4K resolution for precise data work, or a responsive 120Hz Full HD setting for smooth motion during live feeds and dynamic content. One screen with two smart ways to stay productive, without compromise

Deeper blacks and richer detail with VA panel

The VA panel offers exceptional contrast and deep blacks, revealing every nuance between light and dark. Enjoy vivid, lifelike images with minimal light bleed and excellent color depth, especially in darker scenes. Whether watching movies, editing content, or gaming, benefit from consistent picture quality and wide viewing angles that bring every detail to life.

Easy multi-device control with KVM

Easily switch between multiple computers using one monitor, keyboard, and mouse, making multitasking smooth and efficient.

Built-in audio without extra clutter

Enjoy clear, pleasant sound for calls, videos, and music while keeping your desk free of extra speakers, thanks to the integrated audio.

Double the view, double efficiency

Watch two sources at once. Use Picture-in-Picture to overlay a second feed or Picture-by-Picture to split the screen side by side. Perfect for multitasking, comparing content, or staying in control.

Reduced eye strain & fatigue

Work, study or play longer without eye fatigue, thanks to flicker-free technology and reduced blue light emissions. These features help minimize eye strain and improve visual comfort, allowing you to stay focused and productive throughout the day.

How to use

Connect your primary device via USB-C to use single-cable video, data and up to 95 W power delivery. Use the integrated USB hub to attach peripherals and connect a second computer to the extra inputs; the built-in KVM switch allows switching control between systems with one keyboard and mouse. Select the appropriate display mode in the monitor OSD or with the remote control: 4K 3840×2160 for detailed work or 1920×1080 at 120 Hz for smoother live or dynamic content. Adjust brightness, picture settings and blue light filter in the OSD for optimal viewing.

Recommendations

For extended use sessions enable the flicker-free mode and reduced blue light setting to minimise eye strain. Use the 4K mode for productivity and content editing, and switch to Full HD 120 Hz when monitoring live feeds or video with fast motion. If wall- or arm-mounting, ensure the VESA mount supports the weight and size of a 43" monitor.
